Where does come from?

This hijacker is another release from the clandestine malware developer that labels its browser hijackers with the “by SaferBrowser” label. This infamous malware creator is known to our researchers, and they have linked this particular browser hijacker to other releases by it. The list of similar hijackers includes names such as,, and These are just a few examples that have been released recently, but there are plenty of SaferBrowser hijackers you can get accidentally.

Furthermore, most of them have dedicated download websites from which you can get the accompanying browser extensions. The website that hosts is called This site states that it will help you determine your Internet speed, but that is an outright lie and all you will get by downloading it is this hijacker.

How does work?

Researchers have found that it will change the homepage of Firefox, and Internet Explorer and the new tab page of Chrome. Furthermore, it will replace the search provider of Firefox and Chrome.

The search results contain promotional links from this browser hijacker and by clicking them, you generate income for other people. It is fair to say that in most cases the promoted links are safe, although their practical use is rather questionable. However, on more rare occasions this browser hijacker might show you ads that promote potentially unwanted programs and adware, so you should steer clear of them.

As mentioned at the beginning, this hijacker will collect certain information about you. When you use this hijacker’s services, you automatically agree to share information that includes but is not limited to comments, name, email or mailing address. Non-personally identifiable information includes data such as URLs, search queries, browsing history, and so on to customize the ads to make more money. Moreover, if that was not bad enough, the developers can share this information with third parties such as their advertising partners.
